Area Forecast Discussion National Weather Service Sioux Falls SD 1028 PM CST Thu Nov 30 2023 .KEY MESSAGES... - Cooler temperatures prevail across the region tomorrow, followed by a warm up heading into next week. Well above average temperatures return by mid next week. - Mostly dry weather expected to prevail throughout the period, with a very low probability (10-20%) for light snow Saturday night along and east of IA/MN Highway 60. && .DISCUSSION... Issued at 242 PM CST Thu Nov 30 2023 Once again, ample sunshine and mixing along with a lack of snow cover is helping us warm more than expected this afternoon. Temperatures have warmed into the upper 30s to mid 40s despite breezy north/northwesterly winds gusting around 25 mph. Expect winds to taper off late this afternoon into the evening. Soundings and some other hi-res guidance indicate that patchy stratus or fog may develop tonight as winds become light or briefly calm. Will leave out of the forecast for now, given low (< 20%) confidence in occurrence. Lows tonight fall into the teens to lower 20s. Clouds increase as a mid level wave passes to the south. We'll stay dry with the moisture and forcing off to the south. The increasing cloud cover will likely be a spoil sport for those hoping to catch a glimpse of the Northern Lights overnight. For Friday, although we'll see less favorable mixing and more cloud cover than the last few days, raised highs a couple of degrees from the previous forecast toward the higher end of guidance since we've overperformed on highs the last two days. Weak CAA and easterly flow along with cool high pressure helps keep us on the cooler side with highs just below to near normal in the 30s. Lows Friday night fall into the teens and 20s once again. Mid and upper level trough slides east late Friday through the weekend, ejecting out of the Rockies into the Plains Saturday into Sunday. We'll see a few waves move through the broad scale troughing during this time. We should stay mostly dry during this time, although locations along and east of IA/MN Highway 60 could see some light snow. 30.12z models - including ensemble data - have dropped off in probability of measurable precip (>= 0.01") for Saturday night into Sunday, with now only a 30% or less. Although the NBM was dry with no pops, did add some low (15% or less) pops for this period. Not confident that we'll be completely dry, and would like to see another model run or two of the downward trend before removing flurries/light snow entirely. Based on soundings, any precipitation should fall as snow, so have removed all other p-types. Little to no accumulation is expected. Temperatures through the weekend remain near to above normal with highs in the upper 30s to mid 40s and lows in the upper teens to mid 30s. Troughing to the east keeps us in northwesterly flow for the early part of next week. Guidance continues to show a clipper moving through Monday night. Have kept NBM (with less than 10% pops) for now, as guidance seems to be less consistent in the 30.12z runs with timing, strength, and location of this system. Monday brings the start of near to above average temperatures. Mid and upper level ridging builds in and slides overhead mid next week. We'll continue to see a warming trend, with above average temperatures. There are decent chances (30% in southwestern MN to 60- 70% in south central SD) that temperatures exceed 50 degrees across the ensembles. Have leaned on the higher end of guidance maintaining the NBM, especially given the more favorable flow pattern to warm above expectations. Periodically breezy winds with dry weather is expected. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1028 PM CST Thu Nov 30 2023 VFR conditions are expected through the TAF period.
